This invention relates to stove and furnace construction, the primary object of the invention being to provide a structure which may be incorporated in a stove or furnace to increase the heating capacity of the stove or furnace, thereby reducing the fuel consumption to a minimum.

With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a vertical sectional view through a furnace constructed in accordance with the invention.

Figure 2 is a sectional view taken on line 2 2 of Figure 1.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Figure 4 is a sectional View taken on line -d of Figure 2.

Referring to the drawings in detail, the body portion of the stove or furnace, includes a front wall 5, rear wall 6, side walls 1, a bottom 8, and a top 9, the top of the body portion being formed with an opening through which the pipe I extends, the pipe Ii) carrying off air which has been heated, and which is to be distributed to rooms or areas to be heated.

As shown, a baffle plate indicated at Il extends inwardly from the front wall of the body portion, the side edges of the baffle plate Il being secured to the side walls 'I of the body portion. At one end of the bale plate II, is a wall I2 that extends upwardly and contacts with the wall I3 or partition which extends horizontally from the rear wall of the body portion, and engages the front wall 5 thereof. Spaced from the partition I3, and disposed in horizontal relation therewith, is a partition I4 that extends inwardly from the rear wall of the body portion, terminating in spaced relation with the front wall 5 thereof.

A pipe indicated at I5 extends through the partitions I3 and I4 and establishes communication between the passageways formed by the partitions II, I3 and I4.

The reference character I6 designates a horizontal partition which is spaced from the partition I4, the partitions I4 and I6 being connected at their inner ends by means of the vertical wall I'I, providing an air compartment. One end of the compartment is open at I8, so that air may pass inwardly filling the compartment.

The pipe lo, which extends through the top of the body portion, extends through an opening formed in the partition I6, establishing communication between the compartment formed by partitions I4 and I6, with the atmosphere, at the top of the body portion.

The fire-box of the stove or furnace is indicated at I9, and due to the construction shown and described, it will be seen that products of combustion will pass upwardly around the partitions, and heat the outer surfaces of the partitions forming, the various air passageways through the furnace.

An opening 20 provides a means whereby a suitable stovepipe may be connected with the body portion for carrying off' the products of combustion.

Due to the fact that the air to be heated must take an irregular course through the body portion, it will be seen that the air will become thoroughly heated and exhausted through the pipe I0 to the area to be heated.

Due to the increased heating surface, the heat units required to heat the air, will be reduced to a minimum.

What is claimed is:

A heating stove comprising a body portion including a front wall, rear wall, and side walls, said body portion having la fire-box, spaced upper and lower plates extending inwardly from the front wall providing with said side walls a rectangular air passageway communicating with the atmosphere at the front end thereof, a vertical wall closing the rear of said passageway, the rear wall of the passageway being spaced from the adjacent wall of the body portion, said upper plate extending to the rear wall of the body portion, the side edges of said upper plate being spaced from the side walls of the body portion, spaced upper and lower plates extending inwardly from the back wall of the body portion providing with said side walls a rectangular air passageway extending inwardly from the back wall and open to the atmosphere at the rear of the body portion, and the front end of the latter air passageway being spaced from the front of the body portion, a vertical wall closing the front end of the latter passageway, a pipe connecting the passageways, a pipe connected with the upper passageway and extending to the top of the body portion and dividing the space above the upper passageway into a heat passageway, and said body portion having a stove-pipe opening in the wall thereof, the stove-pipe opening being disposed above the upper passageway.
